CATL will start supplying cylindrical batteries to BMW in 2025

According to the official public account of CATL, CATL and BMW Group announced on September 9 that they have reached a long-term agreement. Starting from 2025, CATL will provide BMW Group's "new generation" models. The pure electric models of the architecture are supplied with cylindrical batteries. According to the agreement, CATL will supply BMW with new cylindrical batteries with a standard diameter of 46 mm. These products will be produced in two battery factories located in China and Europe, with each factory supplying BMW with an annual production capacity of up to 20GWh .

According to officials, driven by the new cylindrical battery of the CATL era, BMW's sixth-generation eDrive electric drive technology, which is mounted on the BMW Group's "new generation" model architecture, is the best electric vehicle technology in terms of energy density, charging speed and cruising range. A big leap.

Based on the common vision of both parties to build a sustainable and circular battery value chain, CATL will prioritize the use of renewable energy power and reused materials to produce high-performance batteries. Meanwhile, raw materials such as cobalt and lithium used to produce the new generation of batteries are sourced only from certified mines.

According to BMW Group's official Wechat news, the new cylindrical battery specially designed for the "new generation" model's electronic and electrical architecture can increase the battery life by up to 30% (WLTP) . Compared with the fifth-generation square cells, the negative electrode of the sixth-generation cylindrical cell has higher nickel content, decreased cobalt content, and increased silicon content in the positive electrode. The volumetric energy density will increase by more than 20%.

The new cylindrical cells are available in a standard diameter of 46 mm and in two different heights. The battery system will play an important role in the body structure of the "new generation" model. Depending on the model, the battery will be efficiently integrated into the body structure, reducing space occupation, thus achieving perfect integration of the battery and the body. The space occupied by the original battery module will be greatly optimized.

The voltage platform of the battery, powertrain and charging technology of the "new generation" model will also be increased to 800 volts, thereby optimizing the energy supply of the DC fast charging station. Up to 500 amps of current can significantly increase charging power. Thanks to this, the charge time of the high-voltage power battery is reduced by up to 30% from 10-80%.

At the same time, the BMW Group is continuously working on the further development of energy storage systems. The sixth-generation cell technology will also offer, for the first time, the option to use lithium iron phosphate (LFP) as the cathode material, further avoiding the use of raw materials cobalt and nickel in the cathode material. The company is also advancing the development of solid-state batteries (ASSBs), with the goal of applying solid-state high-voltage batteries to mass-produced vehicles by 2030.

BMW said that in order to meet the demand for battery cells for "new generation" models, the BMW Group has awarded more than 10 billion euros worth of battery cell production requirements to two partners, CATL and EVE Energy. contract . The two partners will build two cell factories each in China and Europe, each with an annual capacity of 20 GWh. In addition, BMW will also look for partners to build two more battery cell factories in the North American Free Trade Zone.

BMW officially said that by the end of 2025, the BMW Group plans to deliver more than 2 million pure electric vehicles worldwide. From the mid-20s, pure electric "new generation" models will make a significant contribution to the BMW Group's sales, and the BMW Group will further accelerate the penetration of pure electric models. By 2030, the BMW Group's pure electric models will account for 50% of its global sales. At that time, the other three brands of the BMW Group will also be fully electrified: the Rolls-Royce brand will complete the electrification of all products; the BMW Motorrad urban travel series will be fully electrified; the MINI brand will also be fully electrified from the early 2030s Towards full electrification, providing customers with zero-emission driving pleasure.
